To all whom it may concern.'

Be it known .that we FRANK AsHwoRrH HoL'r, a subject of the ling of the', United Kingdom of Great Britain and Ireland,and resident ofV Noon Sun House, Whitworth Road, Rochdale, in the county of Lancaster, England, and GRrNDnoD KnRsHAw, a subject of the King of the United Kingdom of Great Britain and Ireland, and resident of 62 Market street1 Whitworth, in' the county of Lancaster, England, have invented a new and useful Improvement in Ninding-Machines, of which the following is a specication.

This application is a division of my application iiled Aug. 24, 1915, Serial No. 17 ,182, which is non'7 Patent No. 1,215,025, dated Feb. 6, 1917.

.This invention relates Yto winding machines in which in order that conical or cylindrical packages may be wound in one machine either at different times or in the case of a machine with more than one winding head either at diii'erent times or simultaneously in different parts, the cam for working a thread guide is provided with more than one cam track and the object of this invention is to make much easier, simpler and quicker than they have hitherto beemchanges from or to the vwinding of a cylindrical package to orv from the winding of a conical package and to obviate the disturbance and loss of accuracy in vadjustments scarcely avoidable in the changes of thread guides and their connectionv with different cam tracks in machines of this kind heretofore constructed in which different thread guides are provided to be brought into connection with the .dierent cam tracks when changes are made from or to the winding of cylindrical packages to or from the winding of conical packages.

This invention consists in devices, by which the change toor from the winding of a cylindrical package from or to the winding of a conical packagecan be effected by a thread guidebeing taken out of connection with one cam track and brought into connection with another cam track While the parts on which the thread guide is movable remain mounted in the winding'machine. Y i

Other parts of the invention are pointed out hereinafter and in the claims' following. I

, Ink the accompanying drawings inl which the same letters and numerals indicatecorresponding parts in ally figures,l an illustrative embodiment of this invention are shown.

In the drawings, Figure l is a front eleva'- tion of part of a winding machine, showing one winding head, Fig. 2 is a plan of part of a winding machine showingparts of two winding heads and one cam serving .for working the traversing thread guides of both heads. Fig. 3 is a side elevation partly in vertical section through part of a ,winding machine and shows one winding head in side elevation. Some of the parts shown in Figs. 1, 2 and 3 are shown in only one or two ofsuch iigures and omitted from the others or other so that other parts may be shown more clearly. Fig. 4L Yis aside elevation partly in vertical section showing on va larger scale a pawl shown in Fig. 3 and parts carrying and used with it. Figs. 5 and 6 are respectively a front and side elevation drawn on a larger scale than Figs. 1, 2 and 3 and showing a-traversing thread guide'. Figs. 7 and 8 are respectively a side view a-nd end view of a die used with atraversing guide. p v

Y Fig. 9 is a frontfelevation of a holder for use in winding cylindrical packages and the arm in which it is mounted for use and the Y Y driving roll and Fig. 10 is a side elevation of such holder and arm.

In the drawings many of the parts shown are of well known construction being very similar to parts shown inthe drawings ofv construction to receive a conical tube or shell bon which a package of yarn or thread may be wound. .c is a driving roll mounted fast upon ashaft l extending lengthwise of Y the machine and revolved Yby any suitable shown as providedwith three cam tracks g, la, h1 formed as grooves in a way usual to work two thread guides z' one at each side of the machine so as to serve for two winding heads the outer cam track 7n' h1 being used in winding conical packages and the central cam track g being used in winding cylindrical packages. Y i

According to .this invention the thread guide of theor each head of a windingV machine is mounted in and movable to and fro along a guide carrier which, serving alone to support and'to guide the threadguide, is itself movable as a whole toward and away from the cam used with such thread guide and is mounted on a support movably mounted in the machine and allowing the guide carrier to be moved as a whole toward and Vaway from the cam while remaining vmounted in the machine7 and enables the die by which the thread guide is made to engage the cam lto be moved to and from the cam and so to be disengaged from one cam track of the cam and be moved into engagement with another cam track thereof while the whole guide carrier and the thread guide remain mounted in the machine and means are provided by which when the die ofthe thread guide has been put into position to be engaged with a cam track appropriate to the kind of package to be wound it may be moved into and held in engagement therewith until it is required to be moved into engagement with another cam track for the formation of another kind of package. For the purpose ofV and according to this invention also the thread guide ofthe or each windinghead is provided in a lpreferred construction with ya plurality of places usually two for the die by which'it is madev to leii'gage the cam' used with it Vin order that when yengaged with any cam track of the cam it may be in proper. relation to the spindle or holder around which a package is to be wound. Y Y

For simplicity Vdescription will be given of the means for supporting and guiding one thread guide though any number of similar means may be provided in accordance with the number of winding heads in a machine. In the construction illustrated in the drawings, guide bars y to support and guide the thread guide c' in its traversing movement are mounted on a frame e with arms 1 to embrace lthe studs p on which the Vlever frame or apron g of the stop motion is pivoted'and with an arm 2 extending downward to carry an adjustable stop and to receive connection of a spring l attached at its lother end to a bracket 5 secured by the bolt 6 and the nut thereon to a rail 7 Vforming part of the framework ofthe machine.

The frame z is movable about'the studs p Vindependently of thel lever frame or apron g and ordinarily the spring 4- which is in tension holds the adjustable Vstop which is shown as a set-screw against the rail 7 in order to determine the position of the frame a and the path of the thread guide but leaves Y in grooves in the framer e socket plates 9 with conical lsockets 10 in which the guideV bar y which is inthe form of a cylindrical rod having conical ends to be inserted in the sockets 10, is mounted. The frame a and socket plates V9 are so formed that the guide bars w jl/ are parallel to one another and to the axis of the driving roll c. The thread guide z' which is provided in the usual way with a notch 11 for guiding yarn is provided with a tubular part 12 to surround and to be slid upon the guide bar y and with a forked part 13 to embrace and to be slid upon thefguide bar and the thread guide i is fitted to the guide bars a: y so as to be. guided thereon with suilicient accuracy but also to be movsocket Vl5 ,when it is to'be engaged in the ad- Y jacent right hand track h of the cam e for a conical package to be wound. The'sockets 14, 15 are formed in such positions relativelyV to the'guide notch 11 that when the die 1:6 is in the socket 14 and engaged with the vadjacent right hand cam track 'it for "the winding of a conical package the guide notch 11 shall be traversed to and fro in a path inv proper position relatively to the roll c `and holder a or a conical package thereon and that when the die 16 is in the socket 1 5 and engaged with the cam track g for the winding of a cylindrical package the guide vnotch 11 shall be traversed to and f ro' in a path still in proper position relatively to :the roll c and the holder 19 or cylindrical package upon it. Y

The holder 19 for use in winding cylindrical packages. is ordinary fforni cornprising a spindle revolub'ly mounted vand held by springs 20 against accidental escape in notches in the lateral extensions 21 ofan arm 22 furnished with a shank 23 adapted tobe inserted andfsecured'in"the arm a2 whenthe holder a is removed therefrom. In`

the case illustrated a set screw24 is used 5 for securing the shank 23' in the arm a2 and removed or slackedfback when the holder a is put intouse. y v Y' v The die 16 when in V'engagement' with either of the cam tracks g h provided for itis moved by the cam e similarlyV toY thread guides oiv the usual construction and arrangement, and the holder aor holder 19 being brought into use according as conical or' cylindrical packages are to` be wound will also work similarly to the'llike parts of machines of the usual construction and arrangement. When change is to be made from or to the winding of a cylindrical package to or from thevwindingv of a conical" '20 package' the changes requisite of either of the holders a and 19 for the other and the tubes or the like on which yarnis to' be wound are made inthe ordinary way and l the frame e is moved about thepivots p vin the direction indicated by the arrow B .so thatsthe thread guide 'iswithdrawn so far from the cam e that the die 16 Ycan be disengagedfrom the cam track g or L in which it may be at'the time Aand when the thread `t0 guide z' being pushedalong the vbars my to a convenient position the die 16 is moved from the one socket'14 or 15 to the other and then the die 16 is brought opposite to the other cam track L or g and is brought into engagement therewith by the frame z being allowed to be moved back by the spring 4 and then windin may proceed. The change of the die 16 rom one of the sockets 14, 15 to the other and Vfrom the central cam track g to the adjacent right hand cam track 72, orthe reverse change is thus accomplished without any other part than the die 16 being dismounted from the machine and the tramel z being simply moved from and allowed to be moved by the spring 4 back to the position determined by the adjustable stop .3 the guide bars a' g/ are always brought back automatically into proper position for winding to proceed. 50 In the constructionhitherto provided the change from or to the winding of cylindrical packages to or from the winding of conical packages has been effected by the change of thread guides and' has involved the dismounting of one of more of the guide bars or other parts on or in which the thread guides are mounted for use and in the dismounting of such parts there has been involved the practical impossibility of putting them 60 back accurately into their previous positions.

The die 16 having a cylindrical shank and the sockets 14, 15 to receive it being cylindrical the removal of the die 16 from one of thesockets 14, 15 to the other and its res- 65 toration to the socket in which it may first the! packages wound yupon `ofthe cam, and a guide carrier for.` suphave been'placedfor use, .involves no possibility of vderangement of adjustments. Changes may be madegin'the details of the device provided Vaccording to this invention within the limits of theclaims folf 7a i *thatA although the provisionof aplurality .75 e
